Delete one testimonial

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is partly covered. The description earns credit by escalating severity with 'Permanently' and 'Irreversible' and by disclosing the confirmation prerequisite, which the annotations do not convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero filler, with the destructive nature front-loaded before the confirmation requirement. Every clause carries information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, but for a destructive single-record delete the description supplies purpose, irreversibility, and the confirmation gate, while annotations carry the safety hints. Nothing essential for correct invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so account, confirm, and testimonial_id are already fully documented in the schema. The description adds only the notion that deletion is single-target; it doesn't elaborate on the confirm flag or account-label semantics. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Permanently delete ... testimonial') with a scoping qualifier ('exactly the requested') that distinguishes it from a batch delete. It does not explicitly name a sibling, but among the listed siblings the delete intent is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description adds a procedural condition ('confirmation required') that implies when the tool can be invoked, but it never states when to prefer this over update_testimonial or how it interacts with siblings. Usage is implied rather than explicitly guided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
